Ed the Plumber

Q: I’ve seen advertising about the “new” touchless-kitchen-faucet technology available for home use. A few years back, I had my plumber install a touchless faucet and found it hard to control.

I have since replaced it, but I’m willing to give it another try if you can give me some good news. What new changes have they made and how do they work?

A: First off, many food experts have told me that touchless-faucet technology in the kitchen is a good idea, especially when handling raw foods. So there is a good incentive for having touchless technology in the kitchen.

The early touchless faucets were basically commercial faucets adapted for home use, and they did not get a very warm welcome. Then faucet manufacturers started designing kitchen faucets that had a touchless option.

This now allows the user to set the desired temperature and flow as normal, but when a hand is waved over the sensor, the faucet will stop.

When activated again, the flow and temperature settings stay the same until the user manually turns off the faucet. This allows constant on-off touchless operation of the faucet while working in the kitchen.
